Homebrew RELEASE Development Thread - RetroArch libnx

i am sitting now, but i stand corrected all

Yeah, it didn't take much to compile. Here's everything I changed. You want a sceenshot of the core's menu... like this?

It just shows the name of the core. It still freezes on a black screen when loading a rom. I'm not even able to open the RetroArch menu while on the black screen.

I can tell that this core wasn't compiled with Salamander. (or was it?)
Also, I don't see any changes to the mman. You should probably use the 3DS one as @julialy had specified, then try to recompile it with that mman.

Yup, cores totally messed up. Even the loading screen is a mess

That's weird, for me, it was working correctly. Only problem for me is that when I load a game, or at some points during gameplay, the video glitches out and I have to change the aspect ratio at least once to get it fixed.
Visited the Discord yet? I have a video of it there.

Ok yeah it's the aspect ratio

yup, the audio is fucking terrible

RE3 was running 100% for me with the test version in any aspect ratio. gonna try this and see if it runs the same but with audio

Freezes when loading a Rom

how well do these cores run now ?psx saturn ?

They work really well (at least the ones I've tried). The only one that works bad is PlayStation but that was just a proof of concept core.

 

[CatmanFan]

I put @julialy's mman.h in the mupen64plus-core/src/sys/ directory just to see how it would change things, and...it didn't seem to change things. Core still compiled as if nothing had happened.
I will be testing the core in a little while, but with Salamander this time, also I will have to change some options within the core like software rendering and dynarec and all that before loading the ROM, just to be safe. Yes, there's a chance that it won't work like Seanny said, but oh well. I'm biting the bullet.

Yabause (Saturn) doesn't work "really well"...unless you use frameskip, but you'll get choppy video and the software being interrupted then resumed on a one-second loop constantly. Threading doesn't affect performance AFAIK. Don't forget Jaguar and 4DO, if "100% full speed" for you means "really well".

 

[kingraa777]

were do the bios files need to be placed how well is yabause running ?

I'm not using salamander, no. My RetroArch isn't up to date, and I kind of prefer having my emulators separate anyways. About mmap and munmap, it's not as simple as compiling 3DS-specific code for the Switch; it'll need to be rewritten. It is helpful, though. But I still doubt the core would work if these functions were properly implemented.

Gz, the core works. 3fps.

Need dynarec and what u left out (not spread across cores either)

 

[CatmanFan]

lol @m4xw beat me to the results

Anyway, I also tried compiling the core (although one version without any normal modifications, one with GLES disabled, and one with a heavily enforced Makefile code; I might have to try and compile a version with ARM dynarec later on), and it actually worked. I was surprised seriously.
But everything runs like shit, especially games that run heavily on 3D graphics (e.g. Mario 64, Wetrix, Tom & Jerry, etc.). Puyo Puyo SUN 64 actually runs a bit faster because it only uses 2D. None of the core options I changed seemed to affect anything, other than controller paks (so far). All the graphics options (including GLide, Angrylion and Rice) don't seem to affect performance either. Trying to change the aspect ratio while the ROM is running instantly freezes the emulator, though. It does work if you change it before loading the ROM, though. So, yes, that means fullscreen N64.

But, everything still runs, or at least tries to, so there's that.

Stay tuned, guys. Coming up next: VICE!! (if it does compile hopefully)

Wait, it actually DOES work? That's hilarious. I thought for sure it would take more than that! I literally threw that together in a few minutes before I started getting ready for work. I'll have to try it again when I get home [emoji14]

Well technically, u did it!

 

[CatmanFan]

Wow, we sure did went from "super hard and can't actually happen" to "successful but still needs a lot of improvement" in a matter of days.

A lot is a underestimate. Dont forget theres 1 whole month of optimizing the shit out of what i could scrap. Full performance will probably require a custom hbloader manifest too.
Dynarec needs to be changed too,to make best use of the syscalls and much more.

Could spend a whole month optimizing this little fucker.

 

[WiiuGold]

Does Mame Work on this ? and what set should get?

Set Video->Settings Aspect Ratio to anything but "Core provided". It gives me a funky resoltion that I honor

You would probably need help from other developers as well, just saying.

Also, holy crap VICE actually compiled. Now let's prepare our SD card for it before I can actually get to test it. Also going to try and test 64DD on Parallel, including the BIOS.
Emulation on the Switch is just getting better and better over time
